Consider the tasks,durations,and predecessor relationships in the following network.Draw the network and answer the questions that follow. (a)What is the expected duration of the project? (b)What is the probability of completion of the project before week 42?

The project described by: has a critical path of length of

Figure 11-1 -Given the network shown in Figure 11-1,assume that completion of A is delayed by two days.What other activities are impacted?

CPM is a probabilistic analysis of managing a project.

PERT

Given an activity's optimistic,most likely,and pessimistic time estimates of 1,9,and 23 days respectively,compute the PERT expected activity time for this activity.

The variance of the project completion time is equal to the sum of the variances of all the activities.

Table 11-4 The following represents a project with known activity times.All times are in weeks. -Using the data in Table 11-4,compute the slack time for activity D.

The first step in planning and scheduling a project is to develop the

Using the data in Table 11-1,compute the latest finish time for activity E.

PERT stands for

A small software development project has four major activities.The times are estimated and provided in the table below. (a)What is the expected completion time for this project? (b)What variance would be used in finding probabilities of finishing by a certain time?

Table 11-4 The following represents a project with known activity times.All times are in weeks. -Using the data in Table 11-4,compute the latest finish time for activity E.

Your company is considering submitting a bid on a major project.You determine that the expected completion time is 150 weeks and the standard deviation is 10 weeks.It is assumed that the normal distribution applies.You wish to set the due date for the project such that there is a 95 percent chance that the project will be finished by this time.What due date should be set?

The activity crash cost is equal to the incremental cost of shortening the project.

PERT was developed for a project for which activity or task times were uncertain.

CPM stands for Comprehensive Project Method.

In PERT,we assume that the project completion time can be modeled by the normal distribution.
